Abstract

<p>The TU Dresden is decisively involved in the development of a sustainable and transparent glazed roof structure. The designed transparent space grid structure is based on a conventional steel space grid, in which all steel members of the compression layer are replaced by glass panes. The glazing transfers large in-plane forces and serves as roof covering.</p><p>Two full-scale mock-ups of a double layer space grid structure in the structure geometries half- octahedron plus tetrahedron and half-Vierendeel demonstrated the feasibility to build such new structures.</p><p>To achieve an individual approval comprehensive testing was conducted. This included small sized testing of block elements for the local load application into the glass edge, in-plane stability tests, walk-on and post breakage behaviour tests and load bearing tests at roof strips of about 15 m length. In the structural tests the glazing had to resist a load with the safety factor of 3.0.</p>
